'rYrEwnrrme MACHINE.

Application filed November 21, 1925 Serial No. 70,490, and in Germany December 6, 1924.

This invention relates to a typewriting machine which as regards its outside dimensions corresponds to the known small travelling or portable typewriters but as regards its working corresponds to a complete typewriter. The object of the present invention is thus to construct a small portable typewriter which, whilst retaining the simple carriage return and the advantages of the known office type of machine, has a complete keyboard and is very strong and stable in design without departing from the usual dimensions of the known travelling machines.

The known forms of portable typewriters differ considerably in ,construction and in arrangement of the keys and type bar mechanism from the larger. sized standard oflice machines and the type bars could not, for example, be arranged in a vertical'bank in front of the roller. In consequence the type bars have been arranged to strike downwards on the roller and the radius levers carrying the type move through an angle greater than 90.

In another form of portable machine, the

type bars may occupyone or other of two normal positions for the purpose of reducing the heightone position was occupied when the machine was being transported and the other, higher, position when the machine was in use, whereby the angle of swing of the radius levers carrying the type was reduced when the machine was in use. The large type bar swing of these known forms, in addition to other disadvantages, affects the key touch and the complicated and necessary sensitive setting mechanism increase the prime cost of the machine as well as reduce its stability and durability.

According to the present invention the keyboard is of the normal size, having 44 keys in the form herein described, and the height and overall sizes are similar to those of the portable type of machine. These results are attained by the peculiar arrangement of the key and type bar mechanism and the suitable method of guiding the carriage with the paper roller.

In order to enable the roller tobe as near as possible to the keyboard, Without raising the carriage guide, the type bar bracket is arranged vertically in front of the roller and the radius lever carrying the type is so arranged and operated that it only travbrought els, through an angle of about 90 from its position of rest into its printing position. All setting mechanism is dispensed with and the operation is simplified. The weight of the machine according to the present invention is thus reduced as compared with other portable machines. i

It will be readily understood that such a material increase in the number of keys, under the conditions herein mentioned, renders, it necessary to provide a. noveltype of operating lever mechanism.

- It is known in typewriters to transmit the movement of the key lever to the type bar through an intermediate lever. It is also known to make the key lever in several parts and to cause the key push rod to act on the type bar draw bar by means of a link and through an intermediate lever. It is further known to transmit .the movement of the key against the action of a spring through a bell crank lever engaging-a draw bar and so to the intermediate lever of the type operating mechanism.

Owing to the curtailment of the space left i for the key mechanism, the large number of keys reduces the distance between the separate key levers to such an extent that considerable difficulty arises in connection with the arrangement and support'of the key levers. According to this invention this difficulty is overcome by interposing a connecting piece between the draw bar of the key lever and the intermediate lever used in the known manner for transmitting the movement to the draw bar of the typebar. In addition all' the draw bars from the front row of keys are so formed as to allow the intermediate levers corresponding to the rearrow of keys to swing freely.

Other features and improvements will be I understood from the following specification and the claims.

One form of the invention is illustrated, by way of example in the accompanying drawihgs. in which:

Fig. 13 is a plan view'of a development of the right hand side of Figure 12.

The frame, made up of sheet steel orduralumin, or the like, is composed of side walls a and a. which are connected by a rear 1 wall a as can be seen in Fig. 2. At its front end the open frame so formed is strengthened and'held together by the angle bar a for the key bridge pieces and the parallel arranged transverse bar a which is arranged above the level of the front bar a. Both these bars, as

.can be seen from Figs. 2 and 5, are interconnected by eleven off-set and" step-formed bridge pieces -for the key lever pivots. The transverse stift'eners a anda are bolted to the side walls a and a In addition to the above mentioned transverse stifleners, the side walls are joined at their lower edge by a broad web piece a and a stiffener a, which carries the type bar sector, connecting the inwardly flanged upper edges of the side walls. At the front of themachine the side walls are stepped upwards tothe inward-1y flanged portion and these steps have each an inwardly turned lug for supporting the key guide plates a. v

The stiffener a is stamped-out of a flat late and has broad bearing flanges a see igs. 2 and 3, and a turned down segmental portion a to which the type section proper is fixed. The flanges a are at an obtuse angle to one another.

As mentioned above the side walls are stepped, see Fig. 1, corresponding to the number of rows of keys. Each step is covered by a guard and guide plate; which together form a closed in key board which may conveniently be formed of separate angle bars a. The push rods 1) pass through slots in these'guide plates a" and these push rods are tapered upwards with a reducing taper so that when depressed the push rods 1) pass freely through the slots, but when the keys are in their normal ralsed positions, they are held without rattling when the machine is subjected to vibration as in transport. The slits formed inthe guard plate are conveniently formed by turning downthe sides so as to prevent excessive wear in use. 4

The keys operate the hell eranklevers 0 through their pushrods b which are connected by a pin joint to the said levers. As

already mentioned the bell crank lovers 0 are supported in the novel shaped bridge pieces which have off-set steps and are arranged in wardly extending arm engaged by the push rod of the corresponding key and the downwardly projecting arm, which is shorter, joined to the draw bars e, (Fig. 7).

\ The pin joint of the push rod 1) to the substantially horizontal arm of the key lever e;-

is effected by a pin 0 fixed in the lever arm over which the 'push rod is passed loosely.

A flat spring 0 fixed to the side of the lever .0 also passes over the end of the pin 0 after the push rod 6 is in place and locks the said push rod in position (Fig. 9). Owing to the spring action of the part c which embraces the in 0 the push rod cannot cause rattling.

T e movement of the downwardly projecting arm of the key lever 0 is transmitted by a draw rod 6 to an intermediate lever f to which there is also fixed at its outer free end a second draw rod 0 extending rearwardly to connect with the type bar 9. A direct connection from the key levers c to the intermediate leversf would partially obstruct the depression of the push rods 1). As the push rods 12 of the rear row aretplaeed as near as possible to the type bars so as to reduce the front to back length of the machine, and also as the intermediate lever f is pivoted at its lower end at approximately the same height as the pin joint of the depending arm of the key lever 0 so as to keep the height of the machine within the desired limits, it is clear that a straight and direct connection from the depending arm of the key lever 0 to an intermediate point of the interposed lever f would foul the end 0 of the key lever when the latter was depressed. 1

It is notadequate to give a side ofi-set to the type lever or the draw bar e in order to ensure the free depression ofthe pusher rod band key .lever c, owing to the smallness of the space between the draw bars. Any increase in this space to be effective would involve a material increase in the width of the keyboard and also the spreading apart of the intermediate levers f which are mounted side by side on a common transverse shaft. An increase in the size of the keyboard would be a serious disadvantage as compared with other portable typewriters. The spreading of the intermediate levers f would necessitate such a sharp inclination of the outside draw bars between the intermediate levers f and the type bars 9 that these keys would require a very much heavier touch to operate them.

According to this invention by interposing an upwardly and rearwardly bent connector it between the draw bar a and the intermediate lever f, the draw bars can be arran ed low in the machine as also the pivot' of t e intermediate levers f and the overall height of the machine is thus retained substantially within the limits necessary for depression of the keys of the rear row together with the operation of their key levers 0 located beneath the keyboard. The connector 71. engages the intermediate lever at a point midway between the low' set ivot f and the free end. The lower end of t e connector k is rolled with aside oii-set to form an eye which is threaded on to the end of the draw bar 6. p

The intermediate levers f are mounted on a common transverse shaft f and can be spaced from one another by side extensions on their bosses or by distance washers so that neighboring levers can move freely without affecting one another.

Owing to the large number of keys, the pitch of the intermediate levers f is kept as small as possible. The keys in each row are ofi-set in relation to one another by the amount of this pitch of the intermediate levers. In consequence of this arrangement, the draw bar e of the front row key, if straight, will pass the pin joint 0 of the rear row .key at a distance in plan equal to the pitch of the intermediate. levers f, which is inadequate to ensure that the rear row keys on depression will not foul or be obstructed by the draw bar from the front row key (see Fig. 4) The draw bars e from the' front row keys are therefore bellied as shown where they pass the marrow keys for a sufiicient amount to allow the free working of the rear row keys and key levers. It is to be noticed in this connection that the depending arm of the key lever moves from rear towards the front of the machine and transmits a similar movement to the intermediate lever f, and connector k.

, The draw bars e, as can be seen from Fig. 8 are bent at their front ends upwardly and then horizontally as at e and e, so that on assemblin this machine, the draw bars can be readily hooked into their proper bell crank key levers c which are previously set in position on their bridge pieces (I. The shape of the hook end e is such that it is impossible for the draw bar e to slip out of the eye on the end of the lever c. The adjustability of the eyes of the connectors It on the draw bars e enables accurate and easy setting of the keys of the same row at thesame height.

As can be seen from Fig. 8, the connectors h with their rolled over eyes, the draw bars c with their hook shaped ends and the levers 0 move indifferent but adjacent planes but the push rod 1) is in the same plane as the draw bar a. The bellied portion of the draw bar from the front row key gives am le working clearance to the rear row push ar. O11 depressing a key in the rear row, the corresponding intermediate lever f swings from rear to front. Owing to the oti-set' eye on the intermediate lever, this swinging can take place without obstruction from the depressedkey lever.

.The double armed bar 9 carrying the type is pivoted in a pivot 9 carried by a sector 2'. A connector is couples the draw bar 6 to the short arm of the type bar. A threaded connecting eye or boss is provided on the connector to engage a thread on the end of the draw bar 6 It will be recognized that by depressing a key, '(Fig. 1) the type lever c swings counter clockwise, the draw bar e and connector 71. swing the intermediate lever f clockwise about the axis f and the draw bar e swings the type bar 9 counter-clock- .wise as shown by the arrow, from the posilevers f. For this purpose the stiffener a is stamped out with hooks along its entire lengthas shown in Fig. 2. With this arrangement it will be seen that the springs can be readily inserted, inspected and when damaged renewed.

The transverse stiffener a also acts as the support of the brackets f which carry the pivot shaft f for the intermediate levers f (Figs. 1 and 2). It is advisable to provide three bearings, one in the centre and one at each side of the machine to prevent undue bending of the pivot. The pivot shaft i may be prevented from swinging with the intermediate levers in any suitable manner, as for instance by means of clamping pins at the bearings f In'order to facilitate the adjustment -of the parts during assembl all the intermediate levers fare provi ed with a hole f does not pass to the front of the centre of shaft f in'plan. The connector h is coupled to the lever f at such a point that the said point swings with a slight downward ath y when operated. The depending arm 0 the key lever, when in its extreme position in operation lies substantially underneath the pivot of the key lever 0. Owing to this setting the type lever is moved with a uniformly accelerated speed. v

In order to give the type carrying ends of 'the type bars suflicient space on their Supporting bed, in spite of the number of keys and the small size of the type bars, the hearing slots of the bars are pitched exceptionally far apart and the angle taken u by the bars on the sector is also exceptional y large. In order that the angle of the outer draw bars shall not be excessive, the pivot shaft of the intermediate levers is brought as close up to the rear row of keys as possible. This measure is rendered possible, as explained above, by the off-set eye on the connector 72.. As can be seen from Fig. 8, the offset of the connector h is in the opposite direction from the hook e and lever c and the roll of the eye is downwards as shown in order to prevent objectionable rubbing or friction between adjacent eyes. It has been found that with any other arrangement, difficulties arlse.

Fig. 4: shows how the long draw bars 6 are bellied in order to give suflicient space for the pin joint of the push bar of the rear row to pass freely. The push bars?) are not arranged centrally on the keys but to one side so to permit of the insertion of'the back spacing and margin release keys in the keyboard.

The stepped bridge pieces d for the key lever pivots are provided at their ends with lugs d and d which are bent in opposite directions, the lug d at the front being bent round whilst still remaining in a vertical plane and the lug d being bent upwardly in the plane of the bridge and then horizontally to be fixed to the underside of the transverse bar a The lug d is turned in the direction opposite to the overhung bearing bush 0 of the key lever c as this enables the back to front length of the machine to be reduced by the thickness of the bridge strip d.

The arrangement of the key lever pivot is shown in Fig. 9 and is designed with a view to durability. The lever c bears on a bush 0 which is fixed by means of a threaded pin 0 having an enlarged head 0 to retain the lever on its hearing. The pin a is threaded into a tapped hole in the bridge piece and a lock nut holds it in place as shown.

The space key shaft a is supported between the rear rows of keys and the type rest 0 and is rotatable in its hearings in the side walls of the machine. The space key arm a. which is fixed to the shafta is so shaped that'it can move freely between adjacent bridge pieces (1. The space key m is provided with an inlay of rubber, celluloid, aluminum or the like. It has been found that rubber makes the best inlay for the space key as it does not become soiled in use.

The type brrs g are pivoted on a common wire g passing through the slots 2' of the sector 2'. The sector 2' is fixed to the cross bridge a". The types are sofixed to the type bars 9 that they do not impinge on the roller at the level of the centre but a short distance above the centre, as shown 1n Fig. 1. This necessitates that the type should be set at the correct angle so that when in printing position, the type face is inclined forwardly at its upper end. Reference has been made sex eral times in this specification to the need for reduction of the height and length of the machine by detailed points of construction. The height of the machine is determined to a great extent by the length of the type bar, that is the distance from the centre of the type roller to the type bar pivot in the ordinary way of'working with a vertical position of the type face in printing. The determining distance is thus the distance from the centre 'of the pivot of the bar to the lowest letter. By the present invention, this usual determining distance is altered as the height from the base of the machine to the centre of the roller can be reduced by the distance between the centre of the roller and the centre of the lowest letter on the type bar. The work can be seen more readily as the printing is efl'ected approximately in the line of vision of the operator. The type rest 0 must be given the same upward inclination to correspond to the forward inclination of the type. y

V This rest is arranged at the sides in a curve corresponding to the radius of the type bar shaft g but at the centre it is flattened. The inclined arrangement of the typerestface and the type together with the flattening of the rest strap 0 in the centre leave suflicient space between the base of the machine and the underside of the rest to admit the free operation of the swinging mechanism of the central type levers withoutnecessitating the lowering of the bearing for the intermediate levers h.

Fig. 12 shows very clearly how the typ bars at the side are spaced apart at a. fairly large angle. The connectors is are inclined at their rear edges as shown in order that they should not take up excessive space when swinging, more particularly in the case of the outside type bars. By this arrangement the connectors never cross the vertical plane from the outer or rearmost point of the type bar to the base of the machine. The carriage is movable backwards and forwards on ball or like'bearings on the rear wall of the machine. The roller n is supported in swing levers for the purpose of raising and lowering it and these levers are pivoted in the rear wall so that the line position will ister.

be retained in both the cap and numeral reg- As there are three rows of t e on each type carrier bar 9 and the printing face of these type is inclined to the horizontal plane through the centre of the roller n, see Fig. 1, the raisin and lowering of the roller will not take p ace in a vertical plane but in one inclined at right angles to the radius shown 1n dot and dash line form as passin through the face of the type carrier in lcated in broken lines in the printing position.

It may be here stated that the most suitable material for the machine frame has proved to be the metal known as duralumin, bu; olther materials may be used if desired.
